Application July s, 1938, Serial No. 218,052 I 12 Claims.

This invention relates to new and useful improvements in tobacco pipes,

An object of the invention is to provide a tobacco pipe so constructed that it may easily be 5 kept clean.

Another object is to provide a tobacco pipe including meanswhereby it may be readily cleaned.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein satisfactory embodiments of the invention are shown. However} it is to be-undtstood that the invention is notJi-mitedto the dew s disclosed but includes 15" allf'such 'va'rianons andr modifications as fall with; in'thespiritoffth' nventionand thfe'scope of the 1 first nventi'on viding'an inner bifurcated portion including r'ela- 10' tivelylong legs I!) and 20 each, when viewed in transverse section, somewhat in the shape of a doubleg wedge (see liiga) having-relatively sharp longitudinal edges 21" :Fiirthe'neachaof theiilegs lSi'aridt-Zfliis'ciifi on ia ev fo' zits' inner e dip portion'sf22ji rigth the gs l 9: an

This last is suggested in Fig. 3 wherein an end portion of a piece of paper 24 has been inserted between the legs l9 and 20, after which the tool is turned on its longitudinal axis to wrap the paper about such legs l9 and 20 to form the mop or swab referred to. As the paper on the tool is inserted into the bowl the operator continues to rotate the tool and this has a further tendency to wrap the paper about the tool and also causes the paper to wipe the side and bottom walls of the bowl.

The bowl being cleaned the passage through the stem Il may also be cleaned. For this operation less paper is used and it is applied to the tool in the manner above described but since a limited amount of paper is employed the same is wrapped rather tightly about the bifurcated portion of the tool. As the legs l9 and 20 are yieldable wrapping of the paper 25 (Fig. 4) about them springs the legs slightly towards one another to allow for the thickness of the paper so that the legs with the paper wrapped about them may be inserted into the passage l3 through the opening I2.

After the insertion the operator continues to turn the tool about its own axis, so as to keep the paper wrapped onto the tool and to have'the paper wipe the inner surface of passage H. Turning movement of the tool in the same direction is continued as the tool with the paper thereon is withdrawn from the pipe. Obviously if desired, mouthpiece I4 may be removed and the tool with the paper thereon inserted into the passage l3 from the rear or outer end thereof. When the cleaning operation has been completed the tool is re-inserted into the pipe as in Fig. 1.

Referring now to Figs. 5 and 6 the pipe there shown includes the bowl 26 carrying stem portion 21 with the outer end of which communicates the mouthpiece 28 detachably connected with the stem as through the metal connecting piece or member 29. Metal member 29 serves also to connect with the mouthpiece 28 a cleaning tool 30 practically identical in construction with the tool I6 with the exception that the tool 30 is secured to mouthpiece 28 and does not include any large head or finger portion and does include a tubular portion 3| extending into and secured to the metal member 29. Tool 30 includes the relatively long legs 32 and 33 corresponding exactly with the legs [9 and 20 previously described and including relatively sharp longitudinal edges 34 and relatively sharp ends 35.

When the tool is in the pipe as in Fig. 5, smoke may pass from the bowl 26 into the stem 27 through the space between the legs 32 and 33 and then into the passage 36 of mouthpiece 28 through the opening 31 in the reduced tubular portion 3| of the tool. When the pipe of Fig. 5 is to be cleaned the tool is withdrawn therefrom and being secured to the mouthpiece, as best illustrated in Fig. 6, may be used 'as described in connection with Figs. 3 and 4, the mouthpiece 28 functioning as a finger or hand piece for the tool 30.

Having thus set forth the nature of my invention, what I claim is:

1. In a tobacco pipe includinga bowl and a hollow stem portion communicating with the bowl, said pipe having an opening in its front wall in alignment with and communicating through the bowl with the opening through said stem, a metal cleaning tool extending through said opening and into the stem and including a bifurcated portion providing a smoke passage between the bowl and stem portion and a pair of spaced simultaneously operable entrances from the bowl into said passage, said tool withdrawable from the pipe for manipulation in cleaning said bowl and stem, and a finger piece on one end of the tool for manipulating the same and comprising a portion of enlarged diameter shaped to abut the front wall of the pipe bowl about said opening therein when the tool is not in use.

2. In a tobacco pipe including a bowl and a hollow stem portion communicating with the bowl, said pipe having an opening in its front wall in alignment with and communicating through the bowl with the opening through said stem, a metal cleaning tool extending through said opening and into the stem and including a bifurcated portion and spaced simultaneously operable entrances from the bowl into said passage providing a smoke passage between the bowl and stem portion, said tool withdrawable from the pipe for manipulation in cleaning said bowl and stem.

3. A tobacco pipe cleaner comprising a metal member including a bifurcated portion, and said bifurcated portion having the opposing surfaces of its legs cut back at both longitudinal edges whereby to provide flaring grooves to facilitate cleaning of said surfaces.

4. A tobacco pipe including a bowl and a stem portion communicating with the bowl, a metal member carried by the pipe and extending into the bowl and stem portion, said member comprising a bifurcated portion providing a smoke passage from the bowl into the stem portion, said bifurcated portion comprising yielding legs having transversely curved outer surfaces extending from the length of the legs and frictionally engaging the walls of the pipe and securing the member therein, and said bifurcated portion having the opposing surfaces of its legs cut back at both longitudinal edges whereby to provide flaring grooves to facilitate cleaning of said surfaces.

5. A tobacco pipe cleaner comprising a metal member including a bifurcated portion, and said bifurcated portion having the opposing surfaces of the free end portions of its legs flaring away from one another.
